Abstractive Summarization of Reddit Posts with Multi-level Memory Networks

Understand

We address the problem of abstractive summarization in two directions: proposing a novel dataset and a new model.

• First, we collect Reddit TIFU dataset, consisting of 120K posts from the online discussion forum Reddit.
• We use such informal crowd-generated posts as text source, in contrast with existing datasets that mostly use formal documents as source such as news articles.
• Thus, our dataset could less suffer from some biases that key sentences usually locate at the beginning of the text and favorable summary candidates are already inside the text in similar forms.
